WebThe enthalpies of solution of hexaglyme in water–N,N-dimethylforamide mixtures have been measured at 298.15 K. To analyze the process of hydrophobic hydration the cage model proposed by Mastroianni, Pical and Lindenbaum was used. The enthalpic effect of hydrophobic hydration of hexaglyme in water has been calculated.
